基于三天线法测量对数周期天线的天线系数

摘要

This paper introduced the measurement principle of antenna factor using Standard Site Method (SSM) based on the ANSI C63.5:2006 standard and set up a measurement system for determing antenna factor of log periodic antenna in Open Area Test Sites(OATS). Then it analyzed and compared the actual test data and the traceable calibration data of standard antennae. In the end, it summarized the measures of improving measurement accuracy, in order to meet the growing demands for tesing antenna factors of high freguency antennae.%介绍了基于ANSIC63.5：2006三天线法的天线系数测量原理，在开阔场地中搭建了对数周期天线的天线系数测量系统，分析比较了标准天线在实际测试与溯源下的测试数据，总结提高测量准确性的措施，满足日益发展的高频天线的天线系数测试需求。
